CAN SOMEONE PLS HELP ILL GIVE BRAINLIEST FOR LEGIT ANSWERS Tyler is saving to buy a new laptop. He has saved $119 so far. Let c represent the cost of the new laptop. Write an algebraic expression that represents the amount of money Noah still needs to save.

c-119= what he still needs to save

c - $119

Step-by-step explanation:

If the laptop costs c and Tyler already has $119, then he needs to save (c - $119) more

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18
